In this tutorial, you learn how to create a Linux virtual machine (VM) with Accelerated Networking. Accelerated Networking is available for Virtual Machine instances that have two or more vCPUs for general purpose VM series (D/DSv2) and compute optimized Virtual Machine M series (F/Fs). After you disable accelerated networking, move the VM, availability set, or scale set to a new size that doesn't support accelerated networking, and then restart them. We have noticed that ACI works well for their scenario but the Networking could be improved. The following picture shows communication between two VMs with and without accelerated networking: Without accelerated networking, all networking traffic in and out of the VM must traverse the host and the virtual switch. For instance, there is no mention of Windows 10 … Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM, greatly improving its networking performance. After you create the VM, you can confirm whether accelerated networking is enabled. Update the accelerated networking property under the network interface: Set the applied updates to automatic so that the changes are immediately picked up: A scale set has VM upgrades that apply updates using three different settings: automatic, rolling, and manual. For the best results, enable this feature on at least two VMs connected to the same Azure virtual network. The NIC bypasses the host and the virtual switch, while it maintains all the policy it applied in the host. 3. We may have later upgraded the OS in place but not re-provisioned the instances, so we never enabled accelerated networking. In this tab, there is an option for Accelerated networking. This high-performance path bypasses the host from the data path, which reduces latency, jitter, and CPU utilization for the most demanding network workloads on supported VM types. It can be enabled only on some instance types. Open the .rdp file, and then sign in to the VM with the credentials you entered in the Create a VM and attach the network interface section. Enabling accelerated networking there should be a one-line change. Otherwise, the option is set to Off, and Azure displays the reason why it can't be enabled. From the Bash shell, enter uname -r and confirm that the kernel version is one of the following versions, or greater: Confirm the Mellanox VF device is exposed to the VM with the lspci command. Accelerated Networking is available on any Azure VM with 2 or more physical cores. Accelerated Networking is supported on most general purpose and compute-optimized instance sizes with 2 or more vCPUs. To create a Windows VM with Accelerated Networking, see Create a Windows VM with Accelerated Networking. At the time of writing, I would like to point out that both the supported operating systems and supported VM instances are not reflective of what Azure is supporting. update: it’s now possible to enable/disable this via PowerShell or CLI. The following example creates a virtual network named myVnet with one subnet: Create a network security group with az network nsg create. It also makes sure that the application keeps running, even if the VF is revoked when the host is being serviced. We can use PowerShell to gather the information about network adapters and then check if they have the accelerated network enabled. Create a network interface with New-AzNetworkInterface with accelerated networking enabled, and assign the public IP address to the network interface. The following diagram illustrates how two VMs communicate with and without accelerated networking: Without accelerated networking, all networking traffic in and out of the VM must traverse the host and the virtual switch. Accelerated networking is available in all global Azure regions and Azure Government Cloud. On instances that support hyperthreading, Accelerated Networking is supported on VM instances with 4 or more vCPUs. If the Mellanox adapter fails to start, open an administrator prompt in the remote desktop session and enter the following command: If you've created a VM without accelerated networking, you may enable this feature on an existing VM. If you receive output similar to the following sample output, accelerated networking is enabled and working. Accelerated Networking is available in all public Azure regions as well as Azure Government Clouds. It also depends on the workload of the CPU that's doing the processing. The Terraform setting to enable: A supported VM size without accelerated networking enabled can only have the feature enabled when it is stopped and deallocated. From the VM overview toolbar, select Connect > RDP > Download RDP File. Applications must run over the synthetic NIC that is exposed in VM. Azure supports SR-IOV, which accelerates networking by allowing VM NICs to bypass the hypervisor and go directly to the PCIe card underneath. For more information on VM instances, see Linux VM sizes. lspci In the supported VM instances and Operating system (CentOS 7.4 which supported) you should be able to see the Accelerated Networking option when you create a VM on portal. If you are using a custom image, and your image supports Accelerated Networking, please make sure to have the required drivers to work with Mellanox ConnectX-3 and ConnectX-4 Lx NICs on Azure. Use Azure Container Instances for data processing where source data is ingested, processed, and placed in a durable store such as Azure Blob storage. To learn more about virtual switches, read the Hyper-V network virtualization and virtual switch article. When creating a virtual machine in the portal, in the Create a virtual machine blade, choose the Networking tab. Applications binding to the synthetic NIC is a mandatory requirement for all applications taking advantage of Accelerated Networking. Example parameter names included myResourceGroup, myNic, and myVm. First, stop the VMs: Once the VMs are stopped, update the Accelerated Networking property under the network interface: Please note, a VMSS has VM upgrades that apply updates using three different settings, automatic, rolling and manual. The stop or deallocate requirement is unnecessary if you disable accelerated networking, because clusters that support accelerated networking also work fine with NICs that don't use accelerated networking. Supported series are: D/DSv3, E/ESv3, Fsv2, and Ms/Mms. Accelerated networking enables single root I/O virtualization (SR-IOV) to a VM. Create a virtual network with az network vnet create. More information on the feature can be found here but this post is not to tell you about what good it does nor how it works.. no, this post is to introduce a new script that will enable/disable the function for you!.
